I'd be similarly shocked if one could write a good article on high temperature physics or group theory while being totally dependent on published reliable sources, because those sources were never written for the purpose of being used to explain the concept to novices.
The best sources for general topics are textbooks actually; reliable, and written to explain concepts. I find the introductions to monographs and papers as useful for WP as the bodies; at least the more articulate writers manage to get in a few words intelligible to the nonspecialist. :-)
I picked those examples precisely because there weren't good or usable textbooks for them. (Or, at least, I asked a random chemistry grad student I had nearby for two topics that would fit that bill and that's what she gave me. Damned if I know what the hell group theory is.)
[[Group theory]] is a branch of mathematics. That article has a rather poor paragraph that points to how chemists us it. To a chemist, Group Theory is a study of the symmetry of molecules or of crystals. The latter is used in X-ray crystallography. The former is used in quantum chemistry and molecular spectroscopy. We do not have an article on it and we should. There are plenty of fairly simple (2nd year chemistry undergrad level) books. The most famous is probably "Chemical applications of Group Theory" by F. Albert Cotton (1963) which lead to it being taught to undergrads. Plenty of people have tried to improve on it since but most failed. I may have a go at an article.
